Voy ...right except all CCH goes through Turnball ,the reason i was told the Custom shop Standard gun costs $3,450 is outlined below in a email response i received from Colt when i asked why so much for the gun!
The Custom Shop Single Action Armies are hand fit and completely assembled by the Master Gunsmith before any of the finishing takes place, additionally the Custom Shop gunsmiths tune the action to the Custom Shop specs. Once fitted the guns are then disassembled and polished by the Custom Shop Master Polishers. We then send the frame for case color to Doug Turnbull and the other small parts are Royal Blued here at Colt.
In short the Custom Shop single action armies get a lot more individual attention then the standard catalog models.
So Voy there you have it the reason for the extra $1,700 or so because a master Gunsmith assembles then polishes your gun... makes sense right?
